[Bug target/118676] Getting "the ABI of passing union with ‘long double’ has changed in GCC 4.4" warning for a function that doesn't take long double and isn't subject to ABI at all (static)

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced:
```


union f
{
   int a;
   long double b;
};


f parse_from() {
        return {};
}
```

the warning should mention return here rather than argument ...
